(CNSNews.com) - A spokesman for Senate Minority Leader Mitch McConnell (R.-Ky.) said the legislation resulting from the tax deal worked out between President Barack Obama and Republican congressional leaders will be posted online on Thursday evening and a cloture vote on the bill could be taken in the Senate as early as Saturday—48 hours after the bill’s posting.

“It will be up tonight and the earliest we will have a cloture vote will be Saturday,” McConnell Spokesman Don Stewart told CNSNews.com. “The earliest it could pass will be Monday or Tuesday.”

In their Pledge to America, released prior to the 2010 mid-term election, House Republicans promised to post bills online at least three days prior to a vote. The Pledge reads: “We will ensure that bills are debated and discussed in the public square by publishing the text online for at least three days before coming up for a vote in the House of Representatives.

President Obama made a similar pledge in his 2008 campaign. “Too often bills are rushed through Congress and to the president before the public has the opportunity to review them,” said the Obama-Biden campaign website. “As president, Obama will not sign any non-emergency bill without giving the American public an opportunity to review and comment on the White House website for five days.”

Article 1, Section 7 of the U.S. Constitution says that all revenue bills—i.e. tax bills--must originate in the House of Representatives. The House Democratic Caucus voted in a closed session today to oppose the tax deal between Obama and the Republican leadership. A Democratic majority will continue to control the House until the end of the year.
